Abstract

본 발명은 디지탈 영상신호처리에 의해 화면 표시크기를 조절할 수 있는 티브이 화면크기 조절장치에 관한 것으로, 시청거리에 연동하여 적정한 화면표시크기를 조절하는 것을 기술적 과제로 하며, 메모리제어 및 이에따른 데이타 스위칭기술로 화면의 실제 영상크기를 조절하여 표시하는 것을 요지로 한다. 따라서 티브이에서 화면크기를 수동 또는 시청거리에 따라 자동으로 조절할 수 있고, 브이씨알에 적용하여 같은 효과를 얻을 수 있다.The present invention relates to a TV screen size control device that can adjust the screen display size by digital video signal processing, the technical problem to adjust the appropriate screen display size in conjunction with the viewing distance, memory control and data switching accordingly The main idea is to adjust and display the actual image size of the screen by technology. Therefore, the screen size can be automatically adjusted according to the manual or viewing distance in the TV, and the same effect can be obtained by applying it to VRC.
